The First Genomic Analysis of Visna/Maedi Virus Isolates in China [PDF]

Frontiers in Veterinary Science, 2022
Visna/Maedi virus (VMV) is a neglected pathogen that damages sheep and goats' nervous and respiratory systems. The virus was discovered 80 years ago and has been endemic in China for nearly four decades; nevertheless, there is little information ...

Ovine TRIM5α can restrict visna/maedi virus. [PDF]

J Virol, 2012
ABSTRACT The restrictive properties of tripartite motif-containing 5 alpha (TRIM5α) from small ruminant species have not been explored. Here, we identify highly similar TRIM5α sequences in sheep and goats. Cells transduced with ovine TRIM5α effectively restricted the lentivirus visna/maedi virus DNA synthesis.

Seroprevalence of Visna-Maedi Virus (VMV) and Border Disease Virus (BDV) in Van province and around [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2018
The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van.

Role of alveolar macrophages in respiratory transmission of visna/maedi virus. [PDF]

J Virol, 2008
ABSTRACTA major route of transmission ofVisna/maedi virus(VMV), an ovine lentivirus, is thought to be via the respiratory tract, by inhalation of either cell-free or cell-associated virus. In previous studies, we have shown that infection via the lower respiratory tract is much more efficient than via upper respiratory tissues (T. N.

Characterization of minimal lesions related to the presence of visna/maedi virus in the mammary gland and milk of dairy sheep. [PDF]

BMC Vet Res, 2019
In order to characterize the complete range of lesions, especially minimal, affecting mammary gland and viral antigen distribution and target cells using immunohistochemistry in naturally Visna/maedi (VM) 84 infected sheep were studied, forty-four from flocks with clinical cases (A) and 35 randomly sampled from two abattoirs (B) together with five ...

Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection. [PDF]

Vet Res, 2011
Abstract This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having a cysteine-rich ricin-type amino-terminal region, a fibronectin type II repeat, eight tandem C-type lectin ...

Amplicon sequencing with Oxford nanopore technologies as a diagnostic alternative for small ruminant lentiviruses in sheep [PDF]

Scientific Reports
In Europe, Maedi-Visna disease has high prevalence rates at the individual and flock levels, respectively, and is regarded as one of the most significant infectious disease in sheep.

Etiology, Epizootiology and Control of Maedi-Visna in Dairy Sheep: A Review

Animals, 2020
Maedi-visna (MV) in sheep is caused by maedi-visna virus (MVV), a small ruminant lentivirus (SRLV) that causes chronic infection and inflammatory lesions in infected animals.

Detection of PrPSc in lung and mammary gland is favored by the presence of Visna/maedi virus lesions in naturally coinfected sheep. [PDF]

Vet Res, 2010
There are few reports on the pathogenesis of scrapie (Sc) and Visna/maedi virus (VMV) coinfections. The aim of this work was to study in vivo as well as post mortem both diseases in 91 sheep. Diagnosis of Sc and VMV infections allowed the distribution of animals into five groups according to the presence (+) or absence (-) of infection by Sc and VMV ...

Investigation, management and control of a maedi outbreak in Norway in 2019-2020 [PDF]

Acta Veterinaria Scandinavica
Background Visna-maedi is a notifiable disease in Norway, and eliminating the disease is a national goal. The import of sheep into Norway is very limited, and strict regulations apply to the movement of small ruminants between flocks and within defined ...
